“…65 Chlorine dioxide was also more effective than chlorine in controlling biofilms on stainless-steel heat exchangers in a water treatment plant 66 and in drip irrigation waterlines. 67 In trials on biofilms containing L. pneumophila in waterline systems, chlorine dioxide (0.5 ppm) reduced counts by 2 to 3 logs and significantly reduced biofilm as seen by SEM. 68 Chlorine dioxide was more effective than chlorine in preventing slime, odors, and foul tastes in a food-processing plant.…”

“…Moreover, clogging substances that attached to the internal dripline walls may detach and transport along the system, leading to more serious emitter clogging. This was mainly due to inappropriate chlorination concentration, injection or storage time (Rav‐Acha et al , ). Besides, Hills and Brenes (), and all confirmed that lateral flushing could improve emitter outflows by 5–8%, but the effect was influenced by irrigation schedule, emitter type and flushing mode, etc.…”

Controlling emitter clogging by reducing clogging substances is commonly used nowadays, but it is merely applied in clogged emitters, so establishing a convenient and pre‐treated emitter clogging control strategy is essential. In this paper, four types of non‐pressure‐compensating emitters were selected for a drip irrigation experiment using reclaimed water. Furthermore, suspended particles' components in reclaimed water treated with four technologies were tested, and then their components' relations with emitter clogging substances were studied. The results showed that clogging substances inside emitters and suspended particles both showed the complicated biofilm structure. The mineral components, relative phospholipid fatty acids (PLFAs) concentrations and dominant microbial communities of clogging substances inside emitters were consistent with those of suspended particles in the same reclaimed water. Mineral components were quartz, alkali‐feldspar and illite (total exceeding 88.0%). The relative PLFA concentrations were 0.7–0.8‰, while the main PLFAs were 12:0, i15:0, 16:0 and 18:0. Moreover, bacteroides, bacillus and cellvibrio were the dominant bacteria. However, solid particles in four types of reclaimed water represented more differences. The mineral components, relative PLFA concentrations and dominance indexes varied by 9.7–29.9, 57.9–253.0 and 2.6–49.0%, respectively. Therefore, an emitter‐clogging control strategy could be established according to suspended particles' components in the same reclaimed water. Copyright © 2016 John Wiley & Sons, Ltd.
