Dewatering As Part of Waste Reduction

Dewatering treatments present a value efficient and environmentally pleasant methodology of reducing the quantity of waste requiring disposal. The role of the modern day filter press is to remove the solids from the sludge and change it right into a dry filter cake. The dry cake can then be disposed of by land fill, incineration or other methods dictated by the Environmental Agency relying on toxicity. The filtrate can then either be re-used on-site for additional cleaning thus saving on mains or river water or disposed of down the drain. This after all is only accomplished if the filtrate is non poisonous and hurtless.

Dewatering not only saves on water but will significantly reduce the quantity of waste to be disposed of; reducing haulage transportation costs, time and labour offering the customer an general reduction in disposal costs. For example, a customer has one hundred tons of liquid waste to dispose of, off site, of which typically only 10% may be stable materials with the remaining 90% filtrate. With using mobile dewatering equipment ninety tons of filtrate will be recycled back to plant, fairly than transporting one hundred tons of liquid off site.

This is a great enchancment on the present scenario the place most liquid waste is disposed of in liquid form by mobile tankers for disposal both to a remedy centre or suitable landfill site.

The conventional routine is that a dewatering professional or technician will make a site visit and carry out a site survey where a sample of the liquid waste might be taken and tested to ensure the waste might be filtered. It can additionally decide the standard of the filtrate and dryness of solid filter cake in addition to the permitted method of cake disposal.

This process will be carried out in a laboratory or on the premises using a test filter press. Once this has been accomplished calculations will be made and a full proposal submitted to the client.

Dewatering is most frequently used in sludge removal as part of lagoon cleaning, drain and sewer cleaning and in just a few instances, tank cleaning. In most situations, dewatering filter presses that are totally mobile are additionally self-contained. An example can be a fully mobile 1300mm2 membrane type filter presses with eighty chambers, providing a cake drop capacity of approx 3.5m3 per cycle. Given that on some products a cycle might be accomplished in a single hour, the items have the potential to deal with and process as much as 30m3 of sludge per hour. The press will be run 24/7 if required though within the case of very large jobs, most contractors will deliver a semi static unit which could be delivered and operational on the identical day. Typically the units will probably be equipped with 2 operatives for the entire operational period.

In Conclusion, dewatering filter press companies provide the fantastic advantage of each a cost saving and an environmental solution. It is a service offered globally and positively a service value contracting.
