Doctor Big Blue Series (Sediment / Carbon)

Big Blue and Big Black Heavy Duty Filter Housings offer the versatility to meet all of your large-capacity filtration needs, including highflow and heavy-sediment applications. The extra large housing allows for greater cartridge capacity, reducing the number of vessels required for high flow-rate applications. Sumps are available in both 10″ and 20″ lengths. The High-Flow Polypropylene (HFPP) cap is available with 3/4″, 1″ or 1-1/2″ NPT inlet and outlet ports. The 1-1/2″ internal port allows a greater volume of liquid to pass through the HFPP cap more rapidly. Big Blue and Big Black Housings are compatible with a broad range of chemicals and are available with or without a pressure relief button. They accept a wide variety of 4-1/2″ diameter cartridges.

Doctor Clack Aerating Iron Oxidizer System

Doctor Clack point-of-entry (POE) Aerating Iron Oxidizer (AIO) filter systems function as a regenerable water treatment unit utilizing oxygen instead of potentially harmful chemicals to rejuvenate and enhance the performance of the selective filtration media. The filtration media provided is specific to the water contaminant or contaminants that your water treatment specialist has identified.

The AIO system utilizes the Clack WSlEE control valve equipped with air injection capability to remove ferrous (or clear water) iron, manganese, and sulfur from the water by both oxidation and filtration. During the regeneration cycle, an air bubble is established in the head space of the filter tank above the media. Then, during service, as untreated water enters the tank, it mixes with the air. Oxygen present in the air oxidizes some of the iron and managese that are present in the water, causing them to precipitate into particles which become trapped in the filter media. The remaining dissolved iron and manganese precipitate out in
the filter bed as they are oxidized by the catalytic reactions occurring on the media surface. 

Unlike other iron filter alternatives, the Clack WSlEE AIO technology is designed for use in a single tank / valve system configuration, reducing both installation and maintenance costs, yet delivering years of trouble-free service. No chemical additives or air compressors are required for operation or regeneration with the Clack WSlEE AIO’s unique and advanced design.


  • Higher flow rates
  • Faster setup time – 10,000 RPM fast-positioning motor with 12 volt DC drive
  • Easy servicing – cartridge-based seal and spacer design for quick and easy replacement
  • Optical technology – optical sensors control the backwash cycle for trustworthy.


  •  Effective in both upflow or downflow systems
  •  Choose from metered or time clock regeneration
  •  Bypass valves of fiber reinforced polymer or stainless steel
  •  Your choice of plumbing yoke connections: .75″, 1″, 1.25″
  •  NPT, BSP and Sweat

Doctor Standard Ultraviolet Series

Model UVD240/320/320E/400/400E/485/600/800/1000/1200/1500

UV Dynamics designs and manufactures Ultraviolet (UV) water disinfection systems. UV water disinfection is a proven, affordable, environmentally friendly technology that can help you to ensure the safety of your water supply.

Extreme weather, spring snow melts and run-off from intensive agriculture activities are all affecting the safety of our private water sources. Even municipal water can no longer be assumed to be safe with boil water advisories becoming more frequent. Compared to chemical disinfection, UV water disinfection can never overdose, has no effect on taste and odour, and no carcinogenic disinfection by-products are produced with UV water disinfection. UV water disinfection is considered effective against cryptosporidium and giardia, pathogens which are almost completely resistant to chlorine. UV water disinfection systems have low operating costs and no tools are required for maintenance or lamp replacement.

All our models incorporate both audio and visual lamp failure indicators along with an annual lamp change reminder timer. Many models also incorporate an isolated low voltage solenoid drive circuit for an optional water shut-off solenoid valve.


  • Flow rate from 8 GPM to 50 GPM (depends on the model)
  • Passivated and polished 304 stainless steel reactor measuring 3.5” x 18”
  • 9000hr long life coated UV lamp
  • Microprocessor controlled UV power source with audible and visible lamp failure alarms
  • Annual lamp change reminder timer
  • Lamp life remaining feature
  • ¾” MNPT fittings
  • Domed quartz sleeve to simplify servicing
  • No tools required for regular servicing
  • Easy-service lamp connector
