Some prefer tweeting about business, technology and some puns or funny tweets. So follow people from your community and also interact, receive follows from them. This way you have the right audience for your tweets.
Hashtags are like the heart of a tweet. Once click and all the relevant content to the hashtag is on your screen, so will be your tweet. If you use the right hashtag, your tweet will reach to thousands of people who are using the same hashtag.
Tweets with media are more likely to be retweeted than ones that don't. Adding media to a tweet catches the attention of people and increases the chances of engagement. ‪#‎digital‬ marketing ‪#‎marketing‬ ‪#‎Twitter‬‪#‎TweetReach‬ ‪#‎SocialMedia‬ ‪#‎SocialMediaMarketing‬ @saleemasraf

Well water iron treatment, Drinking Water Treatment - Potassium Permanganate

 Its an age old method to use potassium permanganate(1% solution) in the well water and then pass it through slow sand filter. It removes Iron from well water.

 potassium permanganate(1% solution)  is effective against: dissolved iron, manganese and hydrogen sulfide.

. Potassium permanganate is a point-of-entry treatment method that oxidizes dissolved iron, manganese, and hydrogen sulfide into solid particles that are filtered out of the water. It can also be used to control iron bacteria growth in wells.

Potassium permanganate is available as a dry, purplish solid. A device injects a solution of potassium permanganate into the water between the water pump and holding tank.

Potassium permanganate oxidizes iron, manganese, and hydrogen sulfide into particles. The particles are then filtered with a multimedia filter which can be either manganese-coated aluminum silicate above manganese-treated green sand or an 8-inch layer of anthracite above manganese-treated greensand. If an insufficient amount of iron, manganese, or hydrogen sulfide is oxidized prior to filtration, the manganese coating on the filter media acts as a backup oxidant to treat any remaining contaminant. If too much potassium permanganate is fed into the water prior to filtration, the excess potassium permanganate serves as a regenerant for the filter media. The water should be colorless when it leaves the filter.

When treating water to remove iron bacteria, a solution of potassium permanganate is fed into the well. A concentration of 3.8 to 7.6 grams per gallon has been found to be very effective. After the solution is added in the well, continuous agitation will help loosen and disintegrate sediment and organic material produced by the bacteria, thus enhancing treatment effectiveness. Agitation can be accomplished by turning the well on and off, which brings water up through the well casing and then lets it fall back into the well.

Potassium permanganate is poisonous and irritates skin, so handle it carefully and ensure that there is no excess potassium permanganate in the treated water. The chemical gives water a slight pink tint. Water should be colorless after treatment.
