Frequently Asked Questions
General Dust Suppression
Depending on the nature of the dust problem, we typically require:
- Description of the issue
- Layout drawings / Process flow sheet
- Photos / videos
- Do you have your own installation team?
Based on this initial information we can begin outlining a solution.
This will then lead to further detailed information gathering and possibly a site survey.
Foam Systems
The water does not need to be potable. Foam system have large orifice nozzles that are not susceptible to blocking. Sediment can however affect valves and pumps in the system, sow e filter to 50 micron.
Very hard water may affect foaming efficiency. If this is the case we would need to carry out testing to ensure compatibility.
Our standard foaming agents suppress dust by efficiently dampening the dust particles, using only minimal moisture. They do not contain any additional binders or ‘tackifiers’. In situations where you want to separate the dust, and avoid dust sticking to larger material, this would be the recommended product.
For instances where additional binding of dust particles is advantageous, we have foaming agents with binders. These also provide extended dust control, trapping dust after the material has dried out.
Best-Chem Foam Systems use a specially custom built nozzle, with a large orifice. This eliminates blocking issues and allows optimum foam delivery.
This is very much specific to the individual application. However the foaming agents are supplied as concentrates with dilution rates ranging from 100-500 parts water to 1 part chemical. One of our representatives will be happy to provide you with a tailored calculation, specific to your application.
This will depend on the application. Water addition can range form 0.1-0.5% by weight of material.
The chemical is manufactured in-house our own facility in the UK.
The chemical is supplied in 1,000L IBCs. Bulk deliveries can be arranged on request.
Due to the wide range of projects we undertake, it is difficult to give an broad cost. However, if you speak to one of our representatives, we can obtain some initial information and provide a budget costs.
Capital Cost: Equipment + Installation
Operating Costs: Chemical + Maintenance
Most installations are completed within a week, larger installs can run to 4-5 weeks.
With containerised systems, the plant room is fabricated off site reducing on site installation time. Much of the onsite work can be done during normal operations, with only a limited amount of work requiring shutdowns and plant isolations.
With every install, a Best-Chem Project Manager will meet with the client and agree a safe and efficient installation plan. This will then be documented and submitted for review and approval prior to arrival on site.
Yes, all systems are designed to be activated by the client’s control signals. We can discuss specific requirements and design a system to suit. This includes considering; signalling, alarms, consumption information, tank monitoring, automatic remote operation, operator manual override and ensuring compatibility and compliance with customer Standards.
Yes, Best-Chem are happy to train staff in the operation and maintenance of the system ensuring they are familiar with safety procedures, isolations, operation and maintenance tasks.
In addition to the manual, training handouts and training logs can be provided.
Each system will be accompanied via a manual detailing the weekly, monthly inspections.
We can provide training to your maintenance staff to ensure they are familiar with the maintenance procedures, or we can provide a Service Contract, whereby the equipment is regularly service by our experienced service engineers.
Yes, services are carried out by our dedicated teams of directly employed service engineers. This ensures the continued availability and effectiveness of the dust control system.
Following each service the Client is provided with a detailed report and notified of any recommendations or further action.
The service frequency will depend on the equipment, the site, usage pattern and criticality of the dust control system. They range from monthly to twice a year.
Yes, we have demonstration equipment which can usually be installed within a few hours. The great thing about our Foam Dust Suppression System is that the result in terms of dust reduction is immediate and clear to see.
Misting Systems
No. Best-Chem Misting Systems utilise a high-pressure pump to force water through fine nozzles, thereby generating the mist. There is therefore no need for a compressor.
The systems require a supply of clean, cold potable water at a minimum of 2 bar pressure
The system operates at 70 bar.
The pipework is either High Pressure Nylon tubing, or stainless steel pipes. Depending on the pipework, we have a full range of high-pressure push-fit fittings to assemble the discharge pipework and misting lines.
Systems include 5 and 10 micron sediment filters and an ultraviolet water sterilisation unit.
The average droplet size varies from 3 to 20 microns, depending on the chosen nozzle. Our team can assess your application and recommend the most appropriate nozzle size and configuration.
There are several activation options available, including: sensors, client signals, push button stations, remote control or programmable timers.
Sprinkler Systems
Each system can be divided into multiple zones or areas, with the activations controlled via a centrally located programmable timer. Remote controls are available and we can also now provide an app- or web- based systems.
Yes, flexible daily/weekly schedules can be set up with scheduled activation and run times.
The controllers are very easy to use, and training and manuals will be provided.
Yes, rain sensors are included to automatically pause the system during inclement weather
Sprinkler spray distances range from 3 to 35m. Our team will design an efficient layout for you, considering pipe routes, sizes, coverage, flow and pressures whilst ensuring a cost effective approach.
There are several options. Firstly, with all installations we ensure there are adequate isolation and drain down points. The next option is to automatically control the drain down points and finally we can trace heat the lines. In some instances, a combination of the above may be appropriate for different sections of the installation.
The system will require a supply of clean cold water and will be filtered down to 50 micron. With all water systems we recommend a legionella risk assessment is carried out and the recommended control measures are implemented.
Depending on the water source and expected demand, our team will recommend if a tank is required and what capacity. Supply and installation of the tank can be included in the project scope.
