Excellent effect on water purification and compound odor elimination

Even though a lot of efforts and expenses were invested so far in environmental problems caused by various odors generated from water-quality stabilization and sludge treatment systems of treatment facilities connected with sewage/wastewater, leachate, livestock wastewater, food wastewater and high concentration factory wastewater, it was not easy to deal with consistently reinforced environmental regulations. To solve these problems, the business division and research institution of EPL CO,. ltd. is supplying related products as its excellence has been approved by researching and developing and applying to sites through industry-university cooperation.

Cheongwoo Microorganism Activator

(CWMA, CHEONG WOO Microorganism Activator)
Patented Product

CWMA, which is like a complex nutritional supplement for underwater microorganisms, contains a lot of bacteria and water treatment microorganisms by appropriately mixing drying spawns, organic carbon sources and inorganic nutrients.

  • It can handle load changes quickly by increasing microorganism activity significantly.
  • It is easy for microorganism species to transform when filamentous microorganisms such as actinomyces.
  • It is stored quickly at the time of microorganism shock.
  • It increases microorganism activation of an aerobic tank (aeration tank), a reactor, etc.

Purpose of Use

  • Aerobic tank at a treatment system
  • Supplementing microorganisms in a reactor and increasing microorganism activation (increasing water quality treatment efficiency)

Cheongwoo Microorganism Propagation

(CWMP, CHEONG WOO Microorganism Propagation)

CWMP is a product that increases the total viable cell count significantly by separating dominant strains. It supplements microorganisms quickly when there is shortage of them and also increases microorganism vitality greatly as organic carbon and drying spawns are included.

  • When most microorganisms become extinct as toxic wastewater flows in, it can restore early by new strains.
  • As it increases the number of microorganism strains greatly when high concentration alkaline and acid wastewater flows in, it can handle impact load excellently.

Purpose of Use

  • Seeding initial microorganisms at treatment systems or when test running
  • For supplementation at the time of microorganism impact load

Complex Deodorant

(CWMA-DO, CHEONG WOO Deodorant)
Patented Product

  • Strong deodorization effect immediately after using a product
  • The effect of a product lasts long and it is economical as its dilution factor when using is high.
  • It eliminates the source of odor completely and is easy to use.
  • There is no secondary pollution and it is harmless to humans and domestic animals.

Purpose of Use

  • Eliminating bad smells at treatment systems generating various bad smells (sludge treatment systems, etc.)

Coagulant (Powder and Liquid Product)

Coagulant(Power and liquid produt)

  • Polymer for water treatment system processes
  • Polymer for sludge dehydration system processes
  • Coagulant aids for aluminum sulfate, pre-treatment and dissolved-air floatation

Purpose of Use

  • Water treatment system process (chemicals process)
  • High coagulation and precipitation effect for sludge dehydration
