Cequesta Water applications

Filter Press is a traditional technology for handling sludge dewatering, suffering from intensive labor requirement, Filter Press users are looking for better alternatives. There are applications where this technology can`t easily be replaced, like fine minerals production, that still tolerates Filter Press drawbacks, but for most of the small to medium applications Cequesta Water can offer a viable alternative. Each Filter Press installation requires careful pre-engineering including process, mechanical, electrical and civil, on the other hand the ASP is completely a pre-engineered system; this alone saves about $15,000 per project, making the ASP project less expensive than manual Filter Press.

Small to large size Municipalities and industrial WWTP (wastewater treatment plant) have a continuous need for new and updated solutions for sludge handling equipment under budget constraints during installation and operation. Cequesta Water ASP was designed with these requirements in mind.

Industrial sludge is characterized by its varied plural types; from drinking water sand filters backwash to very fatty food sludge, meat processing, heavy metals sludge, hydroxide sludge, DAF sludge from variety of sources, printing (boxboard printing), paint, resins, electronic, wafers processing, pulp and papers, textile, anaerobic sludge and others.

The food industry is a complex, global collective of diverse businesses that supply much of the food energy consumed by the world population. Only subsistence farmers, those who survive on what they grow, can be considered outside of the scope of the modern food industry.

Paperboard is a thick paper based material. While there is no rigid differentiation between paper and paperboard, paperboard is generally thicker (usually over 0.25 mm, 0.0098 in or 10 points) than paper. According to ISO standards, paperboard is a paper with a basis weight (grammage) above 224 g/m², but there are exceptions. Paperboard can be single or multi-ply. Paperboard can be easily cut and formed, is lightweight, and because it is strong, is used in packaging. Another end-use would be graphic printing, such as book and magazine covers or postcards. Sometimes it is referred to as Cardboard which is a generic, lay term used to refer to any heavy paper pulp based board

Sludge, usually 1-10 DS % ,refers to the residual, semi-solid material left from industrial waste water, or sewage treatment processes. It can also refer to the settled suspension obtained from conventional drinking water treatment, and numerous other industrial processes. The term is also sometimes used as a generic term for solids separated from suspension in a liquid; this `soupy` material usually contains significant quantities of `interstitial` water (between the solid particles).

Dewatering is a physical (mechanical) unit operation used to reduce the moisture content of sludge so that it can be handled and/or processed as a semi-solid instead of as a liquid.
