Acids are widely used in production processes such as etching, pickling, polishing, deburring, metal-raffination, passivation and activation, as well as ore digestion, leaching, nitration, sulfonation, neutralisation, catalysis, ion exchange and many others. There are different types of acids as hydrochloric acid, sulphuric acid, phosphoric acid, nitric acid, fluoric acid and mixtures of these.
In the production process they are taking up impurities as metal ions, metal complexes, organics and solid impurities. Polyfill Microns offers systems to remove these metals from the bath solution thereby enabling the bath to be recycled continuously. For critical conditions, we conduct laboratory and/or pilot studies before offering the system. Some of the systems being offered by Polyfill Microns is:
Impurities can be removed using any one or combination of the following
DM or deionized water is simply water that has had most of the mineral content and dissolved ion content removed. It is just pure water. The cleanliness of the water is rated as its resistance value. It should be noted that pure water will not conduct electricity. It’s the ions in the water that conduct the electricity. Deionization is simply an ion-exchange process in which water flows through resin beds or resin beads. Cation resin exchanges hydrogen ions (H ) for positive ions, and anion resin exchanges hydroxide ions (OH-) for negative ions. Sometimes there are two column of Deionization – one for the Anions and one for the Cations, but the highest quality water is produced by what is called mixed-bed DI or “MBDI” whereby the Cation exchange and Anion exchange resins are mixed together. Separate Anion and Cation columns are now used infrequently because of the superiority and economy of reverse osmosis. Deionized water quality is measured by conductivity or resistivity. In the chart below, resistivity is represented above the line in ohms or megohms and conductivity is below the line measured in microsiemens.
Deionized (or “DM”) high purity water is an essential ingredient in hundreds of applications such as:
Type III Purified Water is considered to be 1 meg ohm to 0.02 ohms or 1 to 50 microsiemens.
Type II Pure Water is considered to be 1 to 10 meg ohms or 1.0 to 0.1 microsiemens.
Type I Ultra-Pure Water is considered to be 10 to 18.2 meg ohms or .01 to 0.0555 microsiemens.

PolyPac packed tower scrubbers are highly recommended for the prevention and efficient removal of inorganic gases, odors, and fumes mainly for exhaust air containing hydrochloric acid and Nitric acid fumes. PolyMist scrubbers are recommended for removing acid mist and fumes from the exhaust air of process bath, mainly for exhaust air containing chromic acid and sulphuric acid. They are used independently or as ‘prescrubber’ to packed scrubber. Vertical Flow Scrubbers are suitable for chemical processes, metal finishing process, semiconductor manufacturing and dozens of other industrial operations generating fumes and gases. Optimum system performance is achieved with systems that combine intimate gas/liquid mixing and low pressure drop.
There are several factors which influence the design of these systems:
CFM
Air flow through the scrubber, based on cubic ft/min.. System capacities range from 500 cfm to 100,000 cfm.
Configuration
Internal vs. external recirculation system, fan location in relation to tower, duct sizes, inlet and outlet plus location of pump systems, tower access service ports, service platform requirement all influence layout.
Standard construction materials include: polypropylene, fiberglass and PVC. Optional materials include high alloy metals such as stainless and Hastelloy®.
Efficiency
Factors to consider in calculating removal efficiency are:
POLYFILL’S RO/NF/UF Membrane systems offer solutions across the full filtration spectrum Nanofiltration for removal of THM precursors, dissolved organics, and softening applications. Reverse Osmosis for total dissolved solids and inorganic ion removal (nitrate, radium). Ultrafiltration and Micron filtration as prefiltration for RO prefiltration and for removal of suspended solids, oil etc.
We provide the best custom manufactured water treatment systems in the industry. Our people will deliver excellent service and support for your project from conceptual and cost-effective design, to construction and commissioning; and throughout the system warranty and operational life of the project.
By including membrane systems as a treatment option, we now offers engineers the broadest range of treatment alternatives available from a single source. We have significant experience in designing and manufacturing filtration, aeration, stripping, flocculation, clarification, and ion exchange equipment for industries.
The best formula for success in treating particularly challenging waters may be a combination of conventional and membrane treatment equipment combined in a single system. By combining the best available technologies of conventional and membrane treatment systems, we offer single-source responsibility for each project

Polyfill Microns incorporates many innovative technological elements:
The system is delivered ‘ready to go’ all that is required is that it is placed on a concrete slab and that inlet/outlet pipes and electricity are connected. It is in essence ‘plug and play’ The system incorporates primary/final settlement and sewage treatment, therefore there is no need for expensive and time consuming civil works such as separate settlement, screens or septic tanks
