Water Treatment


Dairy processing waste water

Waste waters from dairy operations and from processing and manufacture of dairy products can contain significant quantities of high quality fats and proteins.

  • These contribute to very high biological oxygen demand (BOD) of discharge waters.

  • It is also a waste of potential resource if these products are disposed of to landfill or waste ponds.

  • Our calcium bentonite clays have a very high affinity for both fats and proteins.

  • Bentonite clays can be combined with appropriate flocculants to facilitate rapid separation of fats and proteins from dairy waste and dairy processing waste

  • Bentonite clay is suitable for use in stock feeds, when feed grade flocculants are used the recovered fats and proteins can be reintroduced into stock feeds.

  • This enables effective treatment of water to reduce BOD and also recovers fats and proteins that can be used productively whilst at the same time reducing both direct and indirect costs.

Treatment of Grey Water

Treatment of grey water to reduce fats and soaps

Greywater systems divert water from your bathroom and laundry for use in garden irrigation.

Bentonite Clay is perfect in the Treatment of grey water to reduce fats and soaps. Greywater systems divert water from your bathroom and laundry for use in garden irrigation.

Greywater can be defined as any domestic wastewater produced, excluding sewage. Laundry and shower water is what most people understand as grey water.

The main difference between greywater and sewage (or blackwater) is the organic loading. Sewage has a much larger organic loading compared to greywater.

Some people also categorise kitchen wastewater as blackwater because it has quite a high organic loading relative to other sources of wastewater such as bath water.

With proper treatment household greywater can be put to good use rather than wasted down the drain. These uses include water for laundry and toilet flushing, and also irrigation of plants.

Treated greywater can be used to irrigate both food and non food producing plants. The nutrients in the greywater (such as phosphorus and nitrogen) provide an excellent food source for these plants.

Bentonite clay is used as a weighting agent in water high in color and low in turbidity and mineral content. The bentonite joins with the small floc, making the floc heavier and thus making it settle more quickly.
