Environmental friendly technology for industrial automation

We cannot deny that industrial automation has become a major in producing both optimum efficiency and maximum profit. The engineers create a complex human computer interface and system to accommodate a wide range of work. The purpose is obvious, to maximize the production and increase the quality of the product.

Even more, a custom automation solution can be made to give a more flexible workload. Now the automation has allowed companies to switch over from one product to another product effortlessly within short time because the process is automated. It saves time and money in the long term.

If the automation process has run, hence what it needs to be done is the control process and the maintenance. Equipments are priceless investment that works for the shake of human. For that, we have to always maintain, check and inspect to these industrial equipment. One way to do the equipment maintenance and inspection is by conducting helium leak testing. Helium leak testing can be done by electronic process or chemical or the sound-sensitive technologies.

Helium leak testing use enough equipments [of] complex, that is helium mass spectrometer. Spectro is the core of this device. It will analyze the air sample air to measure the helium amount. Measurement process will succeed if the device fully functioning with an experienced operator in the field.

These series of industrial automation have to be really taken care so that it will not yield something that can destroy the environment. Technology must be used in order not to generate dangerous for the ecosystem. For that purpose, environmental friendly technology certainly needs to be put into consideration for every automation effort.

Surveying Service to Help Environmental Impact Assessment

I have been quite a bit involved to environmental project, especially related to environmental impact assessment. So I know the importance of topographic surveying and mapping, water analysis, hydraulic observation and so on. Those are vital for the assessment. These project may require the participation both environmental engineers and civil engineers.

Environmental engineer’s work on environmental assessment related to all environmental impact aspect either potential or hypothetic, then those impacts are then valued its magnitude and significance. Civil engineers, for example a civil engineer in Mandan generally focus on the aspect of building construction planning, measurement, and construction. These activities include the mobilization and demobilization. Therefore, land surveying is a must.

There is a service available that provide data and information about land topographic, photo surveying, cost estimation, including environmental services such as drainage studies, sewer evaluation etc). This will of course significantly accelerate the progress of environmental impact assessment. Therefore, the service like that is beneficial for both the owner of the project or the consultants. In ND, there are Mandan Surveyors that are reliable and professional for doing such data collection and measurement.

Energy-efficient sterilization-UV and Berkey Water Purifier Update

The message was presented by “Steve Spence”

(1) Update on cistern growth problem, Energy-efficient sterilization, UV

A berkey water filter with filter out E. coli, and pretty much anything else you can find in raw water.

We use one for rain and river water.

(2) North Country Energy Fair

We had a great time at the North Country Energy Fair. We had about 20 people attend our “DIY Solar class”, 10 at our “Make your own biodiesel” class, and about 50 attend the off-grid water pumping and filtration class we presented with a panel of 4 others, including Jim Juczak of Woodhenge and Rob Roy of Earthwood. Rich Douglas covered wind pumping, Jim covered deep well hand pumps, I covered filtration, John covered solar pumps and Luke Martin covered well buckets. Rob’s presentation covered pedal powered piston pumps. We gave about 30 rides on our E-Zip electric bike, and everyone had a lot of fun with it. Our DIY
Berkey Water Purifier was a big hit, as was the Nature’s Head composting toilet, and the MRSA and Swine flu resistant cleaning products. Tom Leue presented his Yellowheat veggie furnace.

Water Storage Heat Exchangers Ideas

Some ideas from “thomas holt”

He has been in heavy equipment for about 10 years. He knows that many of the large construction aggregate companies have a precast division. He believes that the water storage system can be utilitized for the heating and cooling of the home either with hydronics or some other similar application. The combination of passive solar energy and solar obsorption panels used in conjunction with a rain water storage containment system is a real possibility and may be put into action.

High Amount of Sulpate in RO feed water

There is an issue of RO (reverse osmosis) feed water that is described below:

Posted by: “adwynchemicals”

Dear All
We are facingthe problem of high sulphate in feed water (tds 9500 so4-9000 ppm)We have to install a RO plant. please guide us how to solve this problem

You may use an anionic exchange resin or precipitation with a barium salt.

Rain Water Storage / Passive Heat Exchange Storage System

Here is a thought about rain water storage:

Thought #1: thomas holt

I’m interested in rain water storage / passive heat exchange storage system. Being very new to the concept, I had thought about the idea while I was visiting the local solar depot in sacramento california. I have been in heavy equipment for about 10 years. Many of the large construction aggregate companies have a precast division. I believe that the water storage system can be utilitized for the heating and cooling of the home either with hydronics or some other similar application.

The combination of passive solar energy and solar obsorption panels used in conjunction with a rain water storage containment system is a real possibility in my thoughts. I am interested in green construction practices and having the storage system is a good start by saving the natural resources, however, I believe there is so much more that it can be used for than simply water storage alone. I watched a program on the television last evening where one of the universities had incorporated a heat exchanger with copper tubing (radiator) which heated the space. The heating and cooling of stored water used in the right way could potentially create a viable way of heating and cooling the home in winter and summer months. I am asking those who read this to respond and relay their idea’s and thoughts about these possibilities.

Thought #2 From: Rob Crook

What are you talking about is a water sourced heat pump. There are a lot of them on the market and the seer ratings on them are very high. The calculation that you need to perform on the system is the heat load of the building and the number of gallons in the cistern and how fast the water is going to heat up or cool down. The temperature can vary but there are energy efficiencies to consider.

RO for Brackish Water

These are inputs about how to treat brackish water:

I have an underground brackish water with a volume of more than 5000 cubic meter and I want to sell it to a water district. The salinity of the brackish water is 12 ppt. Can anybody tell me, if it will be feasible to do reverse osmosis on this brackish water for potable water supply. Can you give me a percentage yield and may be some data that I can use for economic presentation of my proposal.

You have to run the propertary software of some of the membrane manufacturers and check what can be do with that water
