A basic Alar filter is an impressive piece of engineering with just its standard options.

However, Alar manufactures each system to suit the customer's specifications that sometimes require auxiliary equipment.

Alar supplies Auxiliary Equipment such as (but not limited to) the following:

Wastewater Storage Tanks

Alar filters operate in batches. Therefore, the current day's process water needs to be stored until the filter feed tank and/or treatment tank is ready to receive more water.

Typically, the daily process water is strained of debris and fed into a wastewater storage tanks. During the filtration cycle, the holding tank is used as a reservoir to retain incoming [untreated] wastewater.

Wastewater Storage Tanks capacities vary due to the volume of wastewater generated. It is recommended that the Wastewater Storage Tanks would be able to contain an entire day's volume.

Alar manufactures Carbon Steel Wastewater Storage Tanks ranging from 200 to 3,000 gallons. Alar can supply mixers, pumps, level controls, alarms, and electrical control panels.

Alar is also an excellent source for Fiberglass (FRP) and Polyethylene (HDPE) Wastewater Storage Tanks.

Bulk Bag Unloaders

The filter aid bulk bags are supplied with lifting loops in all four corners. These loops are attached to the bag lifting frame hooks and by electric hoist are raised to clear the hopper. The hoist is mounted on a trolley. Therefore, the bag can easily be pushed into place over the center of the hopper. The discharge chute of the bulk bag is placed through an iris valve into the discharge box. The iris valve is then closed, the discharge chute untied, and the discharge box door closed. After opening the iris valve the bulk bag is now ready to dispense the filter aid into the hopper as needed. The hopper, in turn, feeds the lower end of the conveyor that discharges the filter aid to the mixing tank. When the desired amount is delivered, the iris valve is closed and conveyor is stopped.

Vacuum Pump Wastewater Cooling System

Alar uses vacuum pumps that are liquid cooled and require approximately six (6) gallons of water per minute for cooling. The Wastewater Cooling System will combine cooling water with filtrate water to keep the vacuum pump cool.

Filter Aid Economizers

The Filter Aid Economizer allows the system to conserve filter aid and extend operation time by controlling the knife advance in relation to the vacuum pressure being pulled on the filter.

Wastewater Treatment Tanks

Most filtration or dewatering equipment requires liquid solid separation through chemical treatment. In most cases, the treatment is done in batches, and therefore, a treatment tank is necessary.

Treatment tank capacities vary due to the volume of wastewater generated each shift.

During the treatment cycle, a holding tank is used as a reservoir to retain incoming [untreated] wastewater until the treatment tank is empty. Holding tanks should have the capacity to contain an entire day's volume, whereas the treatment tank should contain the volume of at least one shift.

Alar manufactures Carbon Steel Holding Tanks ranging from 200 to 3,000 gallons, and is an excellent source for Fiberglass (FRP) and Polyethylene (HDPE) tanks.

Alar can custom design your treatment tank and provide accessory equipment such as: Mixers, mixer supports, level controls, automatic pH chemical addition systems (complete with make down tanks-mixers-pumps), automatic pH monitoring systems, filter feed pumps, and control panels. Our tanks can be stand-alone or skid mounted.

The Alar Engineering Department employs mechanical, electrical, and design engineers that can custom build a system to match just about any tank specification.

PH Neutralization Systems

Neutralization of water requires pH adjustment. PH Neutralization is typically accomplished by using acidic and alkaline chemical treatment.

Alar manufactures fully automatic PH neutralization systems that consist of a treatment tank with mixer and level controls, automatic pH chemical addition with make down tanks-mixers-pumps, automatic pH monitoring system, automatic filter feed pump, and control panel. The only man power required is to fill the treatment tank, fill two chemical tanks with water and chemicals, and press two push buttons on the control panel. The neutralization system is skid mounted on a structural steel base, pre-wired and pre-piped, for installation by others.

The neutralization system operates as follows: If the treatment tank is empty, the holding tank wastewater is automatically pumped into the treatment tank. This pump will start and stop automatically until the treatment tank has reached a pre-determined treatment level. Then the chemical treatment cycle will begin.

The wastewater is analyzed for pH concentration and the chemicals are automatically added in the proper amount, sequence, time and rate, under controlled agitation.

Chemical Waste Water Treatment Systems
(a combination of Neutralization Systems & Treatment Tanks)

There are two steps in the dewatering process:

1. Chemical Separation (pretreatment equipment)
2. Mechanical Separation (filtration equipment)

Alar manufactures the equipment for both processes.

Most companies offer one filter and outsource the treatment system. Outsource typically means shipped loose or "piece-meal"; the customer will need to hire a contractor to interconnect the control cabinet, chemical feed tanks, treatment tanks, pH metering equipment, pumps, mixers, plumbing and electrical.

Alar builds three filters that are often accompanied by custom designed Alar treatment skids. The treatment system is manufactured at Alar and shipped pre-piped, pre-wired, and mounted on a structural steel skid for easy disconnection and installation. A virtual "plug-n-play" operation.

If your company already has a mechanical filter, then Alar can engineer and build a chemical separation system to meet the specific requirement of your wastewater and filtration equipment.

Before building your treatment skid, Alar will bench test a sample of your wastewater (at no charge) to determine the best chemical solution.

Chemical Waste Water Treatment Systems Operation

Wastewater is received and strained and then fed into a holding tank. During the treatment cycle, the holding tank is used as a reservoir to retain incoming (untreated) wastewater. If the treatment tank is empty, the holding tank wastewater is automatically pumped into the treatment tank. This pump will start and stop automatically until the treatment tank has reached a pre-determined treatment level. Then the chemical treatment cycle will begin.

The wastewater is analyzed for pH concentration and the chemicals are automatically added in the proper amount, sequence, time and rate, under controlled agitation. If pH is not an issue for treatment, then flocculating and coagulating agents are metered in automatically.

Carbon Columns

The purpose of the Flex-O-Star Carbon Column is to remove residual color and organic material in the water coming from the vacuum pre-coat filter.

Under normal operating conditions, one 200-225 pound charge will last four to five months before it needs replacement. This varies from installation to installation, due to different amounts of processed water and concentration of remaining contaminants.

The carbon column is designed for an upward flow of filtrate. This carbon needs to be flooded at all times during the operation. The liquid is pumped into the bottom of the column, through the bottom filter screen. It then flows up through the carbon and out through the top filter screen.

Dissolved Air Flotation Systems (DAF's)

The DAF Clarifier is a wastewater clarification system that combines flotation and settling. This incorporates dissolved or inspirited air to aid in the flotation of fine solids, fats, oils, and greases. Its rectangular design uses less space, and the hopper shaped bottom facilitates easy removal and high concentration of settleable solids. Sludge collectors are provided, equally spaced on the traveling bridge to give complete coverage of the clarifier bottom. The bridge is also equipped with wiper blades that sweep the surface of the clarifier on each forward movement of the bridge. These wiper blades move the float to the incline plate and into the float discharge trough.

In-Line Polymer Injection System

Although polymers are not necessary for an Auto-Vac Rotary Vacuum Drum Filter, polymers enhance the filtering process and increase thru-put of the effluent; ultimately saving in the use of diatomaceous earth filter media.
