Chemical Manufacturer Wastewater Treatment

A chemical manufacturer issued a PO for a new wastewater treatment system from Dynatec. Our customer is in the process of a major plant expansion and needed to meet new, stricter discharge limits. The wastewater is high in oil and grease, BOD, and COD. The new system will consist of an ultrafiltration system followed by a membrane bioreactor (MBR). The performance of this system was proven over several months of piloting. The results confirmed the selection of UF followed by MBR. The BOD in the permeate was regularly non-detect, down from as high as 40,000ppm in the raw wastewater. All other discharge limits were easily met.

Chemical wastewater treatment utilizing membrane systems that range from selective separation of product to wastewater treatment and reuse.  Dynatec Systems has provided many different chemical wastewater solutions.

  • Ultrafiltration (UF), Nanofiltration (NF) and Reverse Osmosis (RO) for selective separation of product for recovery
  • MBR biological treatmentChemical wastewater treatment
  • Wastewater reuse with MBR
  • Conversions of existing systems to MBR
    • Expand existing bioreactor treatment capacity
    • Improve discharge quality
    • Produce water for reuse
    • Reduce surcharge
  • High purity reuse with MBR and RO

Contaminants Removed

  • Organics
  • Inorganic solids
  • Phenol
  • Solvents
  • Oils
  • Acids

Ultrafiltration offers the following advantages over conventional separation:

  • No chemical required
  • Very little labor required
  • Simple mechanical process
  • Less sludge
  • Ability to concentrate the retentate for beneficial use
  • Less space required
  • Overall lower operating costs

Dynatec specializes in extensive RO and NF membrane systems to remove soluble components of wastewater that may not have been removed by primary treatment. In most cases, the purified water can be reused.

RO is capable of rejecting soluble constituents of aqueous streams, such as:

  • BacteriaReverse osmosis
  • Salts
  • Sugars
  • Proteins
  • A wide range of organics and colors
  • Improves the color, taste and properties of the fluid

RO can be used to purify fluids such as ethanol, which will pass through the reverse osmosis membrane, while rejecting other ions and contaminants from passing.

RO/NF systems

The most common use for reverse osmosis is in purifying water. It is used to produce water that meets the most demanding specifications. This differs significantly from other RO systems that are often only designed to treat potable water. Our system is specifically designed to accommodate:

  • Minimize reject volume
  • Variable characteristics
  • Minimize fouling

RO and NF Technology

RO uses a membrane that is semi-permeable, allowing the fluid that is being purified to pass through it, while rejecting the contaminants that remain. Most NF and RO systems are operated in crossflow to allow the membrane to continually clean itself.

Integrated clean-in-place (CIP)

The membrane skid has an integrated CIP system on the skid. This is especially important for wastewater reuse systems because the cleaning frequency of the skid is often higher than in other RO applications. With an integrated CIP system, cleaning is fast and easy, minimizing the operator’s time.

Tubular Configuration:

  • Higher permeate rate
  • Lower rates of fouling
  • Higher concentration of retentate
  • Easier to clean
  • Longer membrane life
  • Low operating cost

Landfill Leachate Treatment Expansion

Dynatec just shipped two new Ultrafiltration systems for a landfill leachate treatment expansion project. These skids are part of an expansion at an existingLandfill Leachate Treatment Expansion leachate treatment plant. The existing Dynatec system treats 250,000 gallons per day. This expansion will allow them to filter 500,000gpd on average. The primary target contaminants at the landfill are heavy metals. The existing UF system has allowed the landfill to successfully reach their discharge limits for metals. Due to this success, they have contracted Dynatec as the leachate production has increased.

Dynatec Systems industry-leading tubular ultrafiltration (UF) system is used to treat a broad range of industrial wastewater by separating insoluble components from waste streams. As a cost effective and simple solution for separating insoluble components and colloidal contaminants from a waste stream, wastewater UF offers significant advantages over conventional separation.

UF is a pressure-driven process that removes the following from wastewater and other solutions:

  • Emulsified oils
  • Metal hydroxides
  • Colloids
  • Emulsions
  • Dispersed material
  • Suspended solids
  • Other large molecular-weight materials

Ultrafiltration systems are also capable of concentrating:

  • Bacteria
  • Some proteins
  • Some dyes
  • Colloidal or emulsified components

MBR RO for Reuse

MBR RO for reuse, A domestic manufacturer of personal protective equipment is undergoing a major plant expansion. The company now needs to treat their wastewater for reuse as they discharge to a small POTW that could not handle the new volumes or contaminant loading. The new wastewater treatment plant is being built in stages. The first system is a relatively small MBR to handle the first phase of their expanded production. The second system is designed to handle their full-scale production, which will only be several months after the first phase is completed. This system includes an EQ tank, MBR with pre and post anoxic tanks and tubular UF, and RO. The system is designed so that all the RO permeate can be reused while the RO reject can be discharged to the local POTW. One of the goals of the MBR is to reduce nitrates from a high initial concentration to very low levels so that the RO reject will meet that total nitrogen limits for discharge to the POTW. The plant is designed so that future expansion is easily achieved. MBR RO for Reuse

Sanitary Wastewater Expansion

Sanitary wastewater expansion of a previously supplied MBR by Dynatec Systems for a mall was recently completed. The original system treated the sanitary wastewater generated at the mall and wastewater from several restaurants on the property. Recent changes at the mall, including the addition of residential units, resulted in greater wastewater volumes. The expansion was relatively fast and easy due to the modular nature of Dynatec’s UF skids. The permeate meets all requirements for direct discharge to the environment and the compact design fits the limited space available at the mall.

Wastewater reuse

Wastewater reuse is achieved at an automotive plant. Wastewater equipment to treat both sanitary and productionUltrafilter wastewater that included oily waste was designed and installed in a new transmission manufacturing facility.  The goal was to treat and purify water for reuse.

Dynatec met these demands by providing a membrane bioreactor (MBR) followed by a reverse osmosis (RO) system.  The MBR reduced BOD, TSS, and oil and grease to non-detect levels.  The RO is used to polish the MBR effluent so that it is suitable for reuse. It is reused in cleaning operations, cooling tower, and all production applications.

80%-90% of the wastewater is purified for reuse.  Additional industrial park wastewater (after primary clarification at the industrial park) is introduced to the system for treatment and purification.  The system is designed to receive 300,000gpd and purify 250,000gpd for reuse.

This novel approach greatly reduced the total amount of wastewater discharged by this plant.  It provided the water needed for production using a comprehensive system that Dynatec designed, supplied and installed.

Ultrafiltration (UF), Membrane Bioreactor (MBR), Nanofiltration (NF) and Reverse Osmosis (RO) are employed by Dynatec for these wastewater projects. Wastewater recovery and reuse has been successfully implemented with industrial and sanitary wastewater streams for:Reverse Osmosis

  • Cooling tower make up
  • Boiler feed
