 Introduction:

 

ChemFeed is the shortened version of Chemical Feed Equipment.  Chemical feed is concerned with the design of systems or equipment for the control and metering of chemicals for water treatment or process control.  Most chemical feed is focused around metering pumps of some type and the injection of a liquid chemical.  Typical applications are for the disinfection of water, pH adjustment of water, solids removal or turbidity control, or heavy metals precipitation.

 

Chemical Mixing and Metering is more than just a metering pump.  When best practices are in place a chemical feed application addresses the key areas of

 

  • Chemical Storage

  • Chemical Delivery

  • Chemical Metering and Control

  • Result validation

 

As water treatment focuses on mechanical means of treatment through devices like micro and nano filtration with membranes, chemical treatment is still required.  Although no chemicals are metered to treat the water; chemicals are used to condition or disinfect the membrane.  An example of this is the chemical feed equipment used at the Chapparal WTP in AZ.  Most of the chemical metering systems were used for the regeneration and treatment of the filters not actual water treatment.  You can learn more about this on our MUNICIPAL WASTE WATER TREATMENT page.

Learn about the industry best practices.

 

pH Control : This section describes what pH is, how it may apply to you, and what you can do to have dominion over it in your process.

 

DISINFECTION: A HUGE part of chemical feeding is about disinfection.  Disinfection applies to the wash water used in commercial food preparation and laundries to some of our most critical disinfection in our drinking water and air handling systems.

 

BOILER WATER TREATMENT : This section lists types of boiler water treatment equipment is around.  Sections include power generation, commercial and packaged boiler water treatment.  The critical items are the same for all but the size and complexity change.  In all cases a boiler requires, O2 removal, pH adjustment, solids removal, and corrosion protection.

 

SOLID LIQUID SEPARATION:  This section covers preparation of additives to aid in solids liquid separation

 

 

POLYMER ACTIVATION AND FEED: THis section covers Chemical feed equipment specific for use with organic and in-organic polymers.  Otherwise known as Polyelectrolyte.  This is the spot to learn all about polymer feeders and Polymer for waste water treatment.  This is one of the largest segments of chemical feed systems and several standard equipment manufacturers exist.  Polymer metering is third in chemical metering after pH adjustment and Disinfection.

 

MUNICIPAL WASTE WATER TREATMENT Learn about chemical feed and control for waste and potable water treatment.  This section includes standard water treatment equipment solutions like polymer feeders and sodium hypochlorite feed, as well as a list of significant engineered to order chemical feed projects across the country.

 

 

METAL FINISHING: This area lists types of pre and post metal finishing processes and the chemical control used in the processes

 

COOLING WATER:One of the largest area's of water treatment is the treatment of water used to cool processes.  Many industries are impacted by the on going costs and performance of the programs used to treat cooling water.  The key factors in cooling water treatment are, corrosion, scale control, microbiological control, and deposit control.

 

modular turn key water treatment:

 

PULP AND PAPER CHEMICAL FEED EQUIPMENT:  Chemicals are used in the process of paper making to give the paper and board the unique properties of each grade as well as to improve process performance and treat waste streams.  Once one of the worst polluters in the world the paper industry in the United States has worked diligently to reduce the impact it has on the environment.

 

Specific areas of chemical use are Sizing, Retention Aid, Microbiological Control, Felt conditioning, wire cleaning, and Water Treatment.

 

STEEL MAKING: Chemical feed is used throughout the steel making process.  Extensive use of cooling water makes cooling water treatment basics like corrosion inhibitor dosing, scale control, deposit control, and microbilogical control the most common applications.  There is use of polymer dosing and blending equipment and the need for thickener control.

 

MINING AND MINERALS:

 

How Metering Pumps Work and What Type to Use For Your Application:  A Section describing metering pumps, the types of metering pumps that exist and why different types exist.  Not all metering pumps are the same!
