AC Clarifier

AC CLARIFIER WATER TREATMENT PLANTS

AWC Water Solutions offers packaged water treatment plants based on the AC Clarifier process. These plants are ideally suited for stable ground or surface waters where turbidity levels seldom exceed 30 NTU.

Our AC plants are custom-designed to meet our clients’ needs. They use a combination of hydraulic “tortuous path” flocculation/clarification filtration and rapid rate filtration to produce potable water with superior quality. The AC Clarifier plant can treat capacities up to 1,500 gpm (8,100 m3/d) per train (multiple trains can be combined for higher flows). They also reliably achieve less than 0.1 NTU turbidity and 2.5-log, multi-barrier protection against Giardia and Cryptosporidium.

Flash mixing

A coagulant added to the raw water precipitates dissolved contaminants and encourages suspended particles to form “flocs”.

  • Multi-chemical injection ports for coagulant, polymer, pH adjustment, etc. provides process flexibility
  • Static or powered mixers are options

Flocculation

As the water passes upward through the upflow clarifier filter, the flocs grow and are partially removed by the coarse media.

  • Acts as both flocculator and clarification zone to reduce filter loading
  • Very compact compared to conventional flocculation and clarification systems
  • Coarse mono media with high angularity
  • Air scour backwash for reduced water consumption and improved cleaning

Filtration

A high-rate media filter removes remaining particles. Solids that accumulate within both the upflow and downflow filters are periodically removed by automatically controlled air/water backwashing.

  • Mono, dual and multi-media options
  • Options for increased iron, manganese and arsenic removal
  • Air scour/water backwash option for reduced water consumption and improved cleaning
  • Optional water backwash with surface wash
  • Nozzle and plenum-type underdrain

Plant Features

Quality tank construction

AWC constructs its tanks out of highly corrosion-resistant marine-grade, 5086 aluminum alloy. This construction eliminates the need for corrosion-protection coatings and prevents premature failures, which can occur with poor surface preparation or coating failures. Sacrificial anodes are used to further increase protection against corrosion. All fasteners in contact with the aluminum are 316 stainless steel to minimize galvanic corrosion. Stainless steel tanks are also available upon request. Our process equipment components can also be supplied for installation into site-constructed concrete tanks or retrofitted into existing tankage. In these circumstances, AWC can provide tank dimensions and other civil criteria.

Electrical systems and control panels

AWC designs, builds, programs and commissions fully integrated automated control and electrical systems. Our systems feature:

  • Integrated UL and CSA approved MCC’s and control panels
  • Fully automatic operation with advanced instruments and controls
  • Remote monitoring, control and SCADA options
  • Industrial quality PLC’s with simple plug-in, pre-programmed modules for reduced training and technical support

Chemical systems

We offer a full range of chemical mixing and dosing systems, including solution tanks, mixers, dosing pumps and safety equipment.

Advantages of AWC AC Clarifier Plants

Corrosion-Resistant

Our plants are fabricated with marine-grade aluminum alloys and stainless steel to provide superior resistance to chemicals and corrosion, resulting in longer life.

Cost-Effective

Our AC Clarifier plants are pre-assembled and pre-tested in our controlled facility, often saving 50 percent or more over in-situ construction. They can also be integrated into pre-engineered building systems for increased savings and reduced schedule. In addition, the high-rate, upflow clarifier and very low mechanical content provide cost-effective clarification while reducing filter loading and minimize costly maintenance and repairs. Their small footprint also reduces building costs.

Simplicity

Our AC Clarifier Plants plants are pre-assembled and pre-tested in our controlled facility, often saving 50 percent or more over in-situ construction. They can also be integrated into pre-engineered building systems for increased savings and reduced schedule.
