WASTEWATER POND UPGRADE
Introduction
Industrial
plants processes such as condensate evaporators, rinse or wash water
(plant or process), boiler blow down, etc... produce different type
of wastewater. Many types of industries including food processing, abattoirs
(slaughterhouse), automotive manufacturing, energy production, oil &
gas refineries, pulp & paper mills, OSB plants, etc... require storage
ponds or tanks for wastewater treatment.
One of the most challenging problems in the wastewater treatment industry
is to treat industrial process water because each type of industry produces
its own unique blend of contaminated water. Furthermore, within the
same facility, the variables specific to an industry are frequently
changing conditions. For example, alternating acid and caustic cleaning
processes in food processing plants will result in large pH variations.
Industrial wastewater treatment generally require treatment of high
organic, solids, oil and grease and heavy metals concentrations.
The reuse of treated water can be is a viable option with significant
economic benefits in regions where potable water costs are high.
Solution
Nowadays, industries have to find cost effective solutions to minimize
ecological effects of discharging poorly treated wastewater into the
environment because of public pressure and increasingly strict effluent
requirements. The type and extent of wastewater treatment required is
designed for each particular manufacturing process.
PNW solution provide and designe ADS aerobic wastewater treatment ponds which
eliminate odors, reduce suspended solids, pathogens, nutrients, organics,
micro toxicity and facilitate oxidization and precipitation of heavy
metals. In order to enhance BOD, solids, oil and grease and nutrient
reduction, PNW combine AquaMats® biofiltration and Bacta-Pur® Bioaugmentation which has been
proven to be highly effective methods.
Results
Reduction of BOD5 and COD levels by 98% and 90%
respectively and buffering of influent pH variations (2 to 12 pH) without
chemical addition are obtained with PNW designed and constructed pre-treatment
facilities with secondary aerated lagoons such as food processing.
