Waste Water And Sewage Treatment

wastewater2 (1)It is possible to recycle and reuse the wastes that are discarded, given that the recycled product is a valuable one. Water discarded from sinks, washing machine, showers baths and dishwashers is referred as Grey Water while the toilet waste is Black Water. 1/3rd of domestic water is spent on flushing. Grey water could be collected and reused for water closet flushing. Grey Water must be treated with disinfectant, or the nutrient rich water could become a perfect environment for bacteria to multiply.

Gardening
This problem is addressed by treatment and filtration of Grey Water. It is possible to use it as such for gardening without any treatment. Soil can filter out any harmful contaminant but water containing detergent or soap is not ideal for gardening as they make soil lose its structure. Grey water must never be used to water food crops. Rainwater can also be collected and used for gardening. This is actually more beneficial to plants than softened water, for drinking then you do need to which water softener is best.

5Composting
The composting toilet may be useful to houses that do not have a connection to main sewage pipes. Houses in remote places, RV, narrow boat or house boat, can benefit through compost toilets. These toilets decompose the wastes into a safer form which can be used for gardening. The size varies from tanks holding two years’ worth of compost to smaller composting tanks that speed up composting by tumbling or raking mechanism. Better forms of these tanks are odorless.

Reed Bed Sewage Treatment
Reed beds need very less maintenance and are eco-friendly. There are three stages in sewage treatments- primary secondary and tertiary. Reed beds belong in the secondary treatment stage. The septic tank effluent is passed through layers of soil and gravel. Reeds are planted in this soil. Reeds help in the breakdown of pollutants by helping the bacteria in the process. These beds are also attractive to wildlife. Vertical reed beds belong in secondary treatment while horizontal reed beds are tertiary.

Water Processing And Recycling

water_process_management_filtration_systemsLancy technologies provide combined systems to decrease the effluent streams. Their experience in the field rages from providing domestic recycling techniques to metal recovery methods that can be used for mining operations. They have developed numerous waste water technologies that can be integrated into different systems depending on the wastewater treatment.

Filtration
Filtration of the waste water is done to separate solid particles and sometimes pathogens. Filtration is done using various membrane materials with differing pore size. The pore size and material of the filter is decided depending upon the nature of the effluent to be filtered. It’s a little different to the water filter and water softener brands for your home.

Metal Recovery
Copper and nickel are widely used metals in various industries for plating the plastics, circuit board printing and numerous other industries that use metal finishing in general. Lancy technology has developed unique technology for addressing the concern of decreased discharge limits. This technology also recovers nickel and copper with a high metal purity of 99.5% and 99.9% respectively.

Rinse water recovery
Rinse Water Recovery System (RWRS) by Lancy technology provides top quality of metal finishing waters that is capable of reducing o completely eliminating waste disposal. RWRS removes contaminants which make reuse of the recovered metals possible.

20160202105532_86103UV Disinfection
UV disinfection makes sure that all the microorganisms and contaminants are dead or removed. Lancy technology has a patented UV disinfection technology. They also have a UV sterilization technology that is much more effective and efficient than any other UltraViolet technology available.

Waste Water Treatment
Industrial waste waters are hard to treat. Wastewater Evaporator System is the best economical choice for processing industrial wastewaters. They are available on markets and are much more viable than other water processing methods. VACUDEST wastewater evaporator has the ability to separate industrial water and clean water. When clean water is separated, the amount of the wastewater reduces which is easy to treat or dispose. There is no liquid discharge in this production.

All You Want To Know About Water Technology

Di water and oil tank for factory

Despite water conservation techniques improving by the years, drought and water scarcity is looming large. Prominent corporate establishments have taken the initiative to invest in water conservation. For instance, the pledge by Coca-Cola and coalition companies to deliver 2,000 water purification systems is an initiative to promote the idea. Water is a growing issue with the increase in population. There is hardly a person, product, organization or community untouched by water. United Nations says that water has become scarce due to the natural and man-made phenomenon.

Though there are adequate water resources across the globe for the 7 billion population, the uneven distribution is the reason for its insufficiency. Much of water is wasted in transportation and pollution. This calls for a need for water management using time-tested technologies. There is a need to drive towards water efficiency. Some of the tips to promote efficient global distribution of water are listed.

002Population rise is triggering water scarcity. The United Nations Statistics informs that 1.2 billion are suffering from water scarcity, and 1.6 billion have no access to water because of water shortage. It means these countries do not have the infrastructure to provide clean drinking water to its people. It is predicted by 2025 around 1.8 billion will be affected by water scarcity and half the world population will be affected by water scarcity. All this goes to prove that water available is the major investment when considering business expansion. This probably comes as a shock to those more interesting in looking at the top 10 water softeners for their home.

It is predicted there will be a rise in treated wastewater supply for irrigation purposes. The water scarcity issue has justified this cause. But the bad news is waste water is wasted in many high-income countries. The water treatment rate has been put at 70 percent, and it further falls to 28 percent in developing and under developed countries. The director of UNU-UIWEH, Zafar Adeel says that vast resource of water is not reclaimed properly. The municipal and industrial water waste has to be separated. The need for thinking of reusing waste water is essential as almost 95 percent of freshwater is made used for irrigation purposes. Converting waste water to drinking water is an expensive exercise and needs a highly regulated environment. It is followed by states like Nevada, Texas, Virginia and Florida.

Simple Methods To Recycle Water

treatmentplantherzogWater is a precious commodity and with every passing day, many cities are experiencing higher water prices. The water systems are getting complicated by the day, with water crisis affecting city dwellers. The best way to get relief from this problem is to opt for recycling water. The water rates are higher in many cities. Water sewage lines are complicated and repairing them is a horrendous task. Dwellers are using twice the water since 2006, and the bills are also rising. With a drought in many states, people are finding it difficult to access clean drinking water.

Water usage has to be limited with water conservation being the top priority. Water recycling is the simple method to conserve water and cut down on water bills. Some of the simple water to preserve water is listed below.

Using a rain barrel can turn out to be the best water resource if you have the time to invest and handy in your approach. Set up a barrel below the gutter’s downspout. Water gets collected when it rains. This can be a better option when compared to the municipal water system for the gardening purpose.

42811Show bucket is another important method to save on water. It is a known secret that a lot of water is wasted before the water is heated in the shower. Next time use a bucket under the shower, and you will notice a lot of water is saved in the process.

Rain Garden uses natural water to quench the thirst of the plants. Rain gardens do not need regular watering. The water is reused for watering the plants. The water does not run off into the sewage system as in regular gardens.

Gray water system can conserve water. Gray water is not sewage water but is waste water. This is the water that does not go down the drain. Gray water is used for laundry or to wash your hands. Gray water is diverted to flush the toilet. It is a complicated process and needs regular maintenance unless plumbing setup.

Excess drinking water can be reused. Left over drinking water can be used on plants. Even unsweetened tea can be used on plants.

Coagulants Used In Water Treatment

UltraVioletCoagulation is a well-known water treatment process and is a primary process and is done using cost effective ingredients. Some of the popularly used coagulants are listed below:
Alum or Aluminum Sulfate has commonly used coagulant in the US. It is used in combination with cationic polymers. Polyaluminum chloride needs fewer pH alterations to produce viable results, especially to reduce sludge. Ferric chloride produces better results than alum. Ferric sulfate is effective in certain types of water and is economical. Ferrous Sulfate is expensive when compared with ferric chloride, but the outcome is excellent. Sodium Aluminate is also a widely used coagulant.

Sometime cationic polymers are used in combination with iron or aluminum coagulants. Many plants widely use cationic polymers though it is expensive in while comparing on par with inorganic coagulants. The pH range is wider, and the less produced is limited. The coagulants chemicals are selected depending on the type of suspended solids that needs to be removed. The water condition and the cost incurred in removing the chemicals and improving the quality of the water.

slide1It is important to select the right coagulant to enhance the quality of the water. A pilot study on available coagulants is important to choose an effective coagulant. Once the coagulant is selected the implementation process is easy. It is important to fabricate the tools and proceed with the civil construction accordingly. The detention time is crucial to improving the success rate of the flocculation process. The equipment selection is crucial in this case.

There are many methods to remove the impurities in the water. The process of removing textile sewage color removal is a tough task. Moreover, in the reverse Osmosis plant the feed water is not uniform. Globally many methods are available, but not all use these methods. Some of the factors for selection include uniform results, technology cost, capable of upgrading and running cost must be affordable.

The Need For Water Analysis

agua-calidadWater analyses are used in residential and commercial projects. Water supplied by the local bodies or city councils are tested for purity while this is not the case with private suppliers. No official body is called upon to test water quality by private water suppliers. This has left homeowners in risk, and it is the responsibility of the homeowner to protect their water supply from harmful ingredients. Open water sources are vulnerable to all kinds of pollution, and it has to be checked for salts and bacteria on a regular basis.

There are many chemical issues like discoloration of water, lime scale, corrosion and rock formation. Using appropriate treatment chemical issues can be treated. There are more than 50EU water tests that can be conducted on water. It is important to check various parameters before validating the quality of the water. Testing for purity is economical and inevitable for the health of your family.

water-filter-lemon-600x300There are a set of parameters defined for home water supplies. The test for bacteria includes faecal and total coliforms. The chemical tests include checking for iron, nitrates, manganese content and alkalinity, pH and water hardness. There is a need for additional tests for lead, copper, arsenic and more. The water examination is conducted in the laboratory. Testing for the appropriate chemicals is important.

It is highly recommended water analysis be conducted keeping in mind the health factors. Water from private sources are untreated and could lead to deadly diseases. Water analysis has to be mandatory for all water suppliers, be it public or private. A sample of the water can be given in authorized laboratories to check for impurities and salts. There are chances that water is discolored after heavy rainfall. When you spot discoloration in the water supply, it is important to send the sample for testing immediately.
