MACH Scrubbers are specifically designed to efficiently remove corrosive, noxious and/or nuisance gases from process or ventilation air streams. The air stream entering the scrubber is first contacted by the scrubbing solution as it drains from the packed bed to the integral sump below. A liquid distributor located above the packing properly distributes the scrubbing solution across the top of the packing. The air stream then moves upward through the packed bed countercurrently to downward flowing liquid. Traveling a torturous route through the packing extends the contact time between air and liquid, as well as increasing the intimacy of gas/liquid contact. The type of gas and the desired removal efficiency will determine the bed depth, packing size, irrigation rate and chemical requirement. The gas then passes through the liquid spray above the packing. Prior to leaving the scrubber, the scrubbed air passes through a mist eliminator (ME1 Mesh Pad or ME2 Chevron Vanes) to remove entrained droplets.

Applications
MACH Scrubbers are ideally suited for service in a wide variety of applications in industries such as chemical, pulp & paper, steel & metal finishing, fertilizer, and pharmaceutical. In addition, these Scrubber has been used successfully for the control of odors generated in water and waste water treatment, laboratory exhausts, heat transfer, and degassifying. They are effective for the removal of corrosive and/or noxious fumes, and mists (5-7 microns and larger) from a gas stream.

Features

• High Efficiency: Proper sizing of the unit, selection of packing and packing depth, irrigation rate, and chemical feed can result in efficiencies of 99% or better. Standard units contain 2^1/2, 5^1/2, or 10 feet of packing. Units are custom designed to the specific requirements of each individual application.
• Low Initail Cost: Preengineered standard designs are available from 400 CFM to 65,000 CFM.
• Low Operating Cost: The static pressure drop at the rated capacity is less than 4" w.c. for the standard 5^1/2 deep bed. In addition, scrubbing solutions can be recirculated using the integral pump. This reduces fresh water consumption and eliminates the need for extra tankage for the scrubber solution.
• Versatile: The static pressure drop at the rated capacity is less than 4" w.c. for the standard 5-1/2 deep bed. In addition, scrubbing solutions can be recirculated using the integral pump. This reduces fresh water consumption and eliminates the need for extra tankage for the scrubber solution.
• Extended service life: The Series 730 Countercurrent Scrubber has been designed with maximum corrosion resistance as a primary consideration. The wide selection of corrosion resistant materials feature Rigidon FRP (fiberglass reinforced plastic) as a standard material with stainless steel, exotic alloy and brick lined construction available.

Equipment Selection
The key factor in selecting the right countercurrent scrubber for a given application are gas volume to be ventilated, type and quantity of contaminants present, and the required removal efficiency.MACH Technical Support will gladly assist in the selection of a countercurrent scrubber, as well as sizing and selection of accessory items, such as pumps, fans, chemical feed systems, etc. to make a complete scrubber system. MACH Sales Department will then provide a specific quotation on the appropriate scrubber and or a system.
