Water/Wastewater Process Design

Pollutech's experienced and capable team of engineers and technologists can undertake any problem related to liquid waste treatment, including treatment process design work for both industrial and municipal effluents, taking a project from initial conceptual stages and providing guidance to those implementing the process design and construction phase. Pollutech has been involved in a number of national and international projects to finalize implementation of industrial treatment plants, including necessary arrangements for equipment supply, detailed engineering, tendering and financing.

The following list of services are available to support our clients:

in-plant sewer sampling and flow measurement to characterize waste loadings;
identification of water to materials conservation, re-use, and segregation schemes to reduce discharges;
conceptual design of alternate treatment systems;
laboratory treatability studies to evaluate alternate treatment processes and select the optimum process design parameters;
on-site pilot plant studies to confirm the process design under actual conditions;
laboratory and pilot evaluations of associated sludge by-products;
preparation of system operating manuals;
english language logic steps for control systems;
project management; and
start-up and de-bugging of the treatment systems.

Over the past decade Pollutech has found one of our major demands to be in the area of "fine-tuning" or "performance upgrading" of existing waste treatment facilities. Pollutech has established an excellent reputation in this field, and has proven on several occasions that an expenditure for "fine-tuning" can easily result in cost savings that exceed professional fees by over three hundred percent. On several occasions the studies have demonstrated that through the utilization of these services, it is possible to significantly reduce or postpone treatment plant expansions, both in industry and municipal services.

Typical examples of Pollutech's effluent treatment experience include, but are not limited to, the following:

In-plant sewer surveys, laboratory and pilot treatability studies and process design of treatment systems for effluents from glue manufacturing, barley malting, starch production, potato processing, chicken processing and metal finishing industries;
