Complete Water Services provides experience and resources that produce innovative solutions to water and wastewater treatment.

The majority of natural waters are not suitable for potable uses. CWS designs systems to handle the unique challenges of high purity water systems – to meet specific needs of your plant and the water quality required.

Whether you have a water or wastewater issue at your plant, need to install a complete water or wastewater treatment system for your facility, or need experienced assistance with a specialized industrial application, we can help. CWS professionals are hands-on, real world designers and operators. We know what it takes to design and build practical, efficient water and wastewater treatment plants, well suited for their purpose and setting. We specialize in providing customized pre-assembled water and wastewater treatment systems that simplify field construction activities. Our systems include package pumping and filtration systems, pH adjustment systems, membrane systems and packaged sanitary wastewater treatment systems.

From oil fields and power plants, to manufacturing facilities, CWS provides effective water and waste water solutions.

Industrial Wastewater

Food Processing, Packaging, and Preparation

The food service industry covers a broad range of manufacturing processes including bread and sweet-good bakeries; meat, fish and poultry processors; vegetable preparation; animal and vegetable oil processing; beverage and condiment preparation.

Wastewater Generation
Although the manufacturing processes may be very different across the food service industry, the wastewater generated has similar characteristics and similar problems including:

  • pH excursions caused by acid and caustic cleaning processes and the use or manufacturing of acidic products such as vinegar (acetic acid) and citric acid.
  • High levels of settleable solids and suspended solids caused by cleaning operations and in-product loss during production.
  • High levels of five-day biochemical oxygen demand (BOD5) and chemical oxygen demand (COD). BOD5 is a 5-day bio-assay type test and can be considered a measure of biodegradability as it relates to wastewater treatment. COD is a chemical degradation test that takes a few hours to complete and is used as a surrogate to BOD5.
  • Excessive fats, oils and grease (FOG) caused during bakery operations, fryer and cooker cleaning; product loss during transfer; and in blending and cleanup operations. It should be noted that each pound of FOG generates approximately 2 pounds of BOD5.

Metal Manufacturing and Metal Finishing

The metal finishing industry covers a broad range of processes including electroplating, electroless plating, anodizing, coatings, etching and chemical milling, and printed circuit board manufacturing. This is the largest group of industries regulated by USEPA Federal Categorical Standards. WASTEWATER GENERATION Although the metal finishing processes vary across the industry, the wastewater generated has similar characteristics and similar problems. Wastewater is generated from a variety of unit process including:

Wastewater Generation
Although the metal finishing processes vary across the industry, the wastewater generated has similar characteristics and similar problems. Wastewater is generated from a variety of unit process including:

  • Machining
  • Cleaning and surface preparation
    • Acid cleaning and surface preparation
    • Caustic cleaning and surface preparation
    • Paint stripping
    • Solvent degreasing
  • Plating and coating
  • Anodizing
  • Etching and chemical milling

Wastewater characteristics include:

  • pH excursions caused by acid and caustic cleaning and plating bath carryover.
  • High levels of heavy metals used in plating operations.
  • High levels of phosphorus resulting from phosphate coating operations.
  • High levels of cyanide which are used to improve the plating process.
  • High levels of total toxic organics (TTO) TTO List associated with oily wastewater and solvents used for cleaning.

Specialty Chemical Manufacturing

Specialty chemical manufacturing covers a variety of manufacturing processes including but not limited to adhesives and sealants, coatings, carbon black, explosives, fatty acids, polymers, glycerin, printing inks, repellents, and cleaning solutions.

Wastewater Generation

The characteristic of wastewater generated from specialty chemical manufacturing varies greatly depending on the type chemical being manufactured. Primarily wastewater is generated as a result of process tank cleaning, housekeeping, and product loss. Wastewater is generally high in biochemical oxygen demand (BOD5), chemical oxygen demand (COD) and total suspended solids (TSS).

Some specialty chemical manufacturers are also regulated under the USEPA Federal Categorical Standards for Organic Chemicals, Plastics, and Synthetic Fibers (OCPSF) category and must meet a variety of limits for parameters associated with their particular category.

Other parameters of concern include:

  • pH excursions
  • High levels
    • Metals
    • Phosphorus
    • Nitrogen
    • Oils and grease
