Our engineers and scientists deliver interdisciplinary solutions to meet a wide range of client needs. We understand the issues associated with the demand for safe drinking water and the safeguarding of ground and surface waters. Our experience ranges from feasibility studies to new facility construction to rate structure analysis for water supply, treatment, storage and distribution, as well as wastewater conveyance and treatment. When significant inflow enters the sewer system, storm-water flows should be included in wastewater treatment plant design.KCI provides a variety of services for the development and upgrade of water and wastewater systems. Typical industrial discharges include wastewaters from the following: To find the volume of industrial flow, actual measurement can be done to ascertain the flow rates. The capacity factor still needs to be applied while calculating design populations. This total is the number of residents to be used in the design calculations.
For hospitals, the calculation can be done by counting the number of beds, plus the number of hospital staff eating three meals at the hospital, plus the number of shift employees having one meal there. To calculate contributing populations, a factor of 3.6 persons per family residential unit can be considered. Secondary wastewater treatment is capable of removing more than 90 percent of suspended solids. The processes used in the secondary treatment are Activated sludge, Aerated Pond, Aerobic-anaerobic ponds, Trickling filter, Chemical oxidation, Chemical mixing flocculation and clarification, Gravity filtration, Dissolved-air flotation with chemicals, Pressure filtration, Anaerobic contact, etc. Secondary wastewater treatment uses biological and chemical means for the substantial elimination of dissolved organics and colloidal materials. Primary wastewater treatment, in general, removes about 60% of suspended solids from wastewater. Other floatable materials like oils, fats, etc are removed using dissolved air floatation treatment. Suspended solid materials from the wastewater are removed by the sedimentation primary treatment. Major processes used in this step are Sedimentation and Dissolved air floatation. The primary wastewater treatment process is the physical or chemical treatment for the removal of materials that will either float or readily settle out by gravity.
